Phase 2 of the metro project will cover 72.09 km with 61 stations and bring connectivity to Electronic City. The cost is estimated to be Rs 26,405.14 crore. Delhi Metro Rail Corporation has already prepared the detailed project reports (DPRs) for four extensions and two new lines. The high power committee (HPC), in July 2011, gave in-principle clearance to proceed with all six phases of Phase 2 Metro corridors. Phase 2 will become operational in 2017.
